Ok the attached files:

This may suggest you don't have CRDA running properly since you're
stuck on world regulatory domain.

`iwlist` shows you have no channels available for initiating
radiation. This is due to the regulatory problem.

Frequencies:
* 5180 MHz [36] (30.0 dBm) (no IR)
* 5200 MHz [40] (30.0 dBm) (no IR)
* 5220 MHz [44] (30.0 dBm) (no IR)
* 5240 MHz [48] (30.0 dBm) (no IR)
* 5260 MHz [52] (30.0 dBm) (no IR, radar detection)
 DFS state: usable (for 162 sec)
 DFS CAC time: 0 ms
* 5280 MHz [56] (30.0 dBm) (no IR, radar detection)
 DFS state: usable (for 162 sec)
 DFS CAC time: 0 ms
* 5300 MHz [60] (30.0 dBm) (no IR, radar detection)
 DFS state: usable (for 162 sec)
 DFS CAC time: 0 ms
* 5320 MHz [64] (30.0 dBm) (no IR, radar detection)
 DFS state: usable (for 162 sec)
 DFS CAC time: 0 ms
* 5500 MHz [100] (disabled)
* 5520 MHz [104] (disabled)
* 5540 MHz [108] (disabled)
* 5560 MHz [112] (disabled)
* 5580 MHz [116] (disabled)
* 5600 MHz [120] (disabled)
* 5620 MHz [124] (disabled)
* 5640 MHz [128] (disabled)
* 5660 MHz [132] (disabled)
* 5680 MHz [136] (disabled)
* 5700 MHz [140] (disabled)
* 5720 MHz [144] (30.0 dBm) (no IR)
* 5745 MHz [149] (30.0 dBm) (no IR)
* 5765 MHz [153] (30.0 dBm) (no IR)
* 5785 MHz [157] (30.0 dBm) (no IR)
* 5805 MHz [161] (30.0 dBm) (no IR)
* 5825 MHz [165] (30.0 dBm) (no IR)

You also don't have certification onus in the kernel and have no radar
detection in interface combinations:

alid interface combinations:
* #{ AP } <= 8,
  total <= 8, #channels <= 1, STA/AP BI must match

You'd have to recompile the kernel yourself and enable the onus and
DFS for ath/ath10k modules if you want to use channels 52-140.

However I would first look into the regulatory domain problem. Do you
have crda installed on your system? (apt-get install crda) Is it up to
date?
